What Customers Say After the Switch
From greenwash-burned shoppers to allergy households — here's what changed when they swapped in Sampson.
Wavy hair that never liked sulfate shampoo — it always left it dry and frizzy. This cleans my scalp without that stripped feeling, and my curls actually behave. Less foam took one wash to get used to.
Colour-treated hair. My old shampoo faded it fast. Switched to this and the colour holds noticeably longer between salon visits. Scalp feels clean, not tight.
Sensitive scalp, no reaction at all — that alone sold me. I do miss a scent, so I added their eucalyptus oil. Wish it lathered a bit more out of the bottle, but the hair result is there.
Read the ingredient list and recognized everything — no SLS, no silicone, no parabens. Fine hair stays light instead of getting that coated, heavy buildup feeling by day three.
What "clean hair" feels like when the detergent is too aggressive
The squeaky-clean feeling is your hair shaft being stripped, not cleaned.
Most drugstore shampoo is built on sodium lauryl sulfate — the same petroleum surfactant dermatologists use as the irritant baseline in clinical patch testing. It over-cleans: it lifts sebum and product residue, then keeps going and strips natural protein from the shaft. Silicone is added back to mask the result.
Sodium Lauryl Sulfate — the surfactant most drugstore shampoos are built on — is the dermatology gold-standard irritant control in skin patch testing, used on 43,000+ patients over 20+ years (European Society of Contact Dermatitis baseline series)
Phthalates hide in personal-care products under the single word "fragrance" — no regulation requires them to be disclosed by name (Health Canada)
Roughly 60% of the surfactants produced globally each year end up in aquatic environments — and they are toxic to aquatic life (Arora et al. 2022, J. Applied Microbiology 133(3):1229–1244, DOI 10.1111/jam.15631)

We Spent 30+ Years Cleaning Up Contamination. Then We Checked Under the Sink. Nous avons passé 30+ ans à décontaminer des sites. Puis nous avons regardé sous l'évier.
Diana Trasente and Angelo Diadelfo are environmental engineers with Master's degrees and over 30 years remediating contaminated soil and water across Canada. They know industrial chemicals intimately — PCBs, heavy metals, synthetic surfactants, petroleum solvents. Diana Trasente et Angelo Diadelfo sont des ingénieurs en environnement avec des maîtrises et plus de 30 ans d'expérience en décontamination de sols et d'eau au Canada.
Then they started reading the labels on their own household cleaners. The same classes of synthetic chemicals they spent their careers cleaning up were sitting in their kitchen, bathroom, and laundry room. Puis ils ont commencé à lire les étiquettes des nettoyants ménagers chez eux. Les mêmes classes de produits chimiques qu'ils passaient leur carrière à nettoyer se trouvaient dans leur cuisine, salle de bain et buanderie.
In 2010, they founded Sampson Eco Shop — applying the same scientific rigor to household cleaners that they applied to environmental remediation. Every product starts with one question: What's actually in here, and is it safe to put down a drain? En 2010, ils ont fondé Sampson Eco Shop — appliquant la même rigueur scientifique aux nettoyants ménagers qu'à la décontamination. Chaque produit commence par une question: Qu'est-ce qu'il y a vraiment dedans, et est-ce sécuritaire de l'envoyer dans un drain?
“Every cleaner we make starts with the same question we'd ask on a contamination site: what's actually in here, and what happens when it goes down the drain?” “Chaque nettoyant qu'on fabrique commence par la même question qu'on poserait sur un site contaminé: qu'est-ce qu'il y a vraiment dedans, et qu'est-ce qui se passe quand ça va dans le drain?”— Diana Trasente, M.Eng. — Diana Trasente, M.Ing.
The Method
Powered by Coconuts. Engineered by Engineers.
A gentle plant-based surfactant system, paired and balanced by Diana and Angelo Diadelfo, M.Eng. — environmental engineers since 2010.
Wet and open the cuticle
Warm water and the gentle surfactant wet the hair and scalp evenly so cleaning happens at the roots, where buildup actually sits — not by scouring the length.
Lift sebum and product residue
Sodium lauroyl methyl isethionate lifts oil, sweat, and styling-product residue off the scalp — a gentler, sulfate-free-leaning surfactant that cleans without the harsh detergency of SLS.
Strengthen, do not strip
Hydrolyzed wheat protein, glycerin, aloe, and cactus oil stay on the shaft as the surfactant clears the scalp — so cleaning does not cost the hair its natural protein.
Rinse clean, no film
Guar conditioning rinses with the lather and leaves no silicone film to build up. Hair is clean and conditioned, not coated — and the surfactant breaks down in wastewater per OECD 301D.

Format Matters
Read the shampoo aisle by the chemistry, not the claims
Three shampoos side by side on the choices that decide whether your hair gets clean or just stripped.
| Sampson Eco Shampoo | Conventional SLS-based shampoo | "Eco" / greenwashed shampoo | |
|---|---|---|---|
| Primary surfactant | Sodium lauroyl methyl isethionate (gentle, sulfate-free-leaning) | Sodium lauryl sulfate / sodium laureth sulfate | Mixed — often still an SLES base |
| SLS | None | Yes (primary cleaning agent) | Sometimes |
| Silicones | None — conditions with guar + glycerin | Common (masks the stripping) | Variable, rarely disclosed |
| Protein / conditioning | Hydrolyzed wheat protein, cactus oil, aloe (real inclusions) | Often trace label-fill, masked by silicone | "Botanical" claims, source rarely disclosed |
| Scent | Ships unscented; choose from 20+ natural essential-oil fragrances | Synthetic — phthalate carrier likely | Single "natural" scent, source rarely disclosed |
| Parabens | None | Sometimes | Usually paraben-free (the easy claim) |
| Biodegradable to OECD 301D | Yes (disclosed on label) | No | Sometimes claimed |
| Formulated by environmental engineers | Yes (Diana + Angelo Diadelfo, M.Eng., since 2010) | No | No |
The format is the difference. Same plant chemistry, same engineering rigor — without the bottle, the water weight, or the synthetic add-ons.
